#2 Seth Rollins isn't cleared to compete, Matt Riddle replaces him
We now move on to our second crazy thing that could happen at SummerSlam that involves NXT's Matt Riddle, and this is definitely the epitome of crazy thing that would be mind-blowing if it happens.
So, a lot has been made of Seth Rollins' rib injury after the brutal attack from Lesnar a few Monday Night Raw's ago, and it seems that the former Universal Champion is going to be less than fully fit when he takes on 'The Beast Incarnate'. But what if he doesn't make it all?
Let's imagine that Brock Lesnar attacks him again before the bell is rung and Rollins is no longer able to fight through the pain and inconvenience of severe internal bleeding. What if Lesnar then challenges anyone to a fight, as he's there already?
Then steps up Matt Riddle, we know he'll be there because he's been announced for the 'Watch Along'. We also know that Riddle has campaigned feverishly for a match against Lesnar, and has even hinted that something might happen on his social media.
In case anyone is doubting the likelihood of WWE putting an NXT rookie against a dominant champion let me just remind you that's exactly what WWE did with Paige (admittedly she was NXT Women's Champion at the time, and Riddle doesn't hold a title, but still).
#1 CM Punk returns
CM Punk returning to the WWE would be absolutely crazy, right? Especially doing it at SummerSlam and putting an end to the rumors he'll be turning up at AEW's 'All Out' later on in the month once and for all.
Now, I certainly don't expect this to actually happen, but given recent events, there's no denying that it could happen if a certain amount of things were to take place. Firstly, we'd need to find out if Punk's recent interview criticising AEW and saying he's done wrestling is a work or not and then we'd need to analyse the likelihood of Punk returning to WWE at all.
But, if for some reason all the chips have fallen in the right way then Punk returning at SummerSlam would be, without a doubt, the craziest thing to happen in the WWE for a long, long time. Just don't go getting your hopes up!
